IMPROVED SUN-BLIND.

Specification forming part of Letters Patent No. 132,438, dated April19, 1864.

To` all whom it may concern:

Be it known that I, JULiUs JEFFREYS, of Upper Norwood, in the county ofSurrey, England, esqnire, a subject of the Queen of Great Britain, haveinvented or discovered new and useful Improvements in Sun-Blinds; and I,the said J ULIUS JEFFREYS, do hereby declare the nature of the saidinvention, and in what manner the same is to be performed, to beparticularly described and ascertained in and by the following statementthereof-that is to say:

This invention has for its object improve ments in sun-blinds. For thispurpose I employ a series of frames made of wire or othersuitablematerial. These frames are suspended by webs orstraps from ablind-case fixed exterior to the window to which the blind is titted.The suspending webs or straps are so placed and the construction of theblind is so arranged that the metal frames may hang (when the blind isdown) horizontally or tilting upward at their outer edge-viz., that partof the frame farthest from the window. The inclination, however, may bevaried. Pieces of canvas or other fabric of suitable form and textureare attached to the. outer edge, and the two sides of each of the framesand the piece of canvas or fabric so attached to either of the frames isalso secured to the inner edge of the frame next above it, except in,the case of the highest frame, and in this case it is attached to a wireor a metal tube carried by the suspending cloth or fabric at the top ofthe blind, which cloth is supported by the straps or webs above referredto. The pieces of canvas or fabric are thus stretched diagonally fromframe to frame, while the top cloth hangs vertically. In order to raisethe blind, cords are employed. They are each attached at one end to theblindcase or a lath or batten screwed up under the head or top of theblindoase. They then pass downward in front of so as to unwind theblindcords and lower the blind, and by releasing the cord abovementioned the spring of the roller will cause it to revolve in thecontrary direction and to raise the blind. The roller-cord may, ifdesired, be led through the window-frame and into the room. In somecases I substitute plates of metal or glass for the canvas-coveredframes. Also when making blinds of such plates of metal or glass Isometimes t them with spherical ends of metal stamped or formedseparate, and afterward secured to the plates.

The blind-case in which the blind works up and down is made of wood ormetal, and has a slip or strip of wood or metal down the sides at theirback and front edges, so that the inner part of the sides have a widegroove for the blind to work in much like an ordinary Venetianblind-case, but I apply to this case a contrivance for keeping the blindhrm from shaking in the wind, and I also use it for keeping the ordinaryVenitian blinds from shaking in the wind. My invention for this purposeconsists in attaching a strip or batten or iillet of wood or metal ofsuitable form by means of jointed or hinged pieces of metal to the fixedstrip of wood or nieta-l running down the inner edge of blind-case, andwhich ltixed strip forms the inner or back portion of the groovereferred to above. The movable strip of wood works on the hinged metalpieces and falls back against the fixed back slip to leave room in thegroove for the blind to ascend or descend, and when the blind isdown. orin use the said movable slip may be pushed forward so as to jamb orpress both ends of the blind firmly against the front strip fixed on thefront edge of the sides of the blind-case. By this means the blind isfixed very firmly from shaking in the wind. I will proceed to describethe drawings hereunto annexed.

In the drawings, Figure 1 is a front view of a sun-blind constructedaccording to my invention. Fig. 2 is a transverse section of the same.Fig. 3 is a transverse sect-ion showing the position of the blind whenraised.

a a is the window with its frame.

b is the blind-case at the top of the window, and c c are the strips orfillets of Wood or metal, oneon each side of the blind case.

d d are frames of iron wire or iron tubes, galvanized, tinned, painted,orjapanned.

e e are suspending-cords attached to the inner edges of these frames,and also at their upper ends to the case b, as is shown.

ff are pieces of canvas or fabric stretched on the frames. h IL are thelifting-cords. They are attached lat one end to the blind-case, and theypass down through eyes in the canvas or fabric in front of theinneredges of the frames d d. They then ascend to the top of the case and arethere attached to the roller ,which may be aspring roller, such as abovedescribed, and the construction of which is well understood byblind-makers, or an ordinary roller with a cordv round it to cause it torevolve to draw up the blind may be employed. The Weight of the blindwill" be sufficient to lcause it to descend when this cord is released.

k 7c are llets or strips of wood which are brought forward by means ofthe hinged metal pieces ll,which cause them to press against the ends ofthe frames d d, as shown in Fig. 2, so as to hold them firmly againstthe front fixed strip or fillet of the blindcase above described, or,where Venetian blinds are used, such llets may be used to cause thelaths to press against the front fixed strips or fillets.

Having thus described the nature of my invention and the manner ofperforming the same, I would have it understood that what I claim is-The combining of the parts 0 d e f h i in a case, a b, substantially asabove described, and combined therewith or with ordinary Venetian blindsof the parts h l, substantially as described. l
